Knowing there is no perfect camera bag, I still ordered the Everyday Backpack Zip because I felt it would come close to meeting my needs. I've been using two backpacks for quite some time, one for everyday carry with computer sleeve and one for nature walks. For everyday use I have my Fujifilm X-T3 with either a Fujifilm 16-70mm lens attached and a Fujifilm 35mm f2.0 in the bag or I switch those around where the 35mm is attached and the zoom is in the bag. I also carry a A5 size journal, Kindle paperwhite, maybe a book and sometimes a 13" Macbook Pro. When headed to one of the natural areas I will bring along Fujifilm 70-300mm lens in the bottom compartment and no laptop. I do not like carrying much stuff and felt the smaller 15L bag would encourage me to carry only what I need, not what I can carry. I'm over 70 and the back is not what it used to be. So far it has worked out. I've not even consider the other two bags I used. I hesitated to order this because of the price but felt I could not evaluate the bag until I used it. Knew if it did not work for me I could return it. When I first received it I thought the laptop sleeve would be to small but it fits nicely. I find it easy to access my camera from the side or my journal from the top. So far I am very pleased with it.
I would love to give my everyday backpack full 5 stars. The overall built quality is great and the design well thought through. However, what really bothers me is that the shoulder straps will not last long, the body-facing material is too soft and delicate. After just a couple weeks of normal carrying, it showed some serious wear and tear (see pictures). The straps show the most wear and tear, where it touches the bagpack's own material. It is a real pity.
After two years of use, I can honestly say that this is the most comfortable backpack I have ever had. The 270-degree zipper gives you the option of opening it like a suitcase, which is extremely convenient for everyday quick packing. I've had an EDBv1 20L and a Sling 10L before, but the EDBv2 15L Zip is the perfect half-measure. It is a pity that there are no magnetic strips like in EDBv2 and holders for hanging straps. I dealt with it myself, a little non-invasive modification. I usually carry a tablet, Tech Pouch and a raincoat inside, but I can easily stuff my SLR camera. Furthermore, I was surprised that the Travel Tripod can be squeezed inside.
